To all whom it may concern:

Be it known that we, WiLLIAii IV. Mc-

citizeiis of the United States, residing, respectively, at Detroit, in' the county of lVayne, Stateof Michigan, and in the borough of Manhattan, city of New York. State of New new and useful Improvements in the Manufacture of Tires, of which the following is a specification.

- Our present invention relates to the manufacture`of tire shoes, and has for its object to provide an improved construction of the same .wherein the advantages obtained by the use of threads or thread fabric, disposed radially of the tire shoe, or both radially are obtained', at the saine time minimizing certain disadvantages attendant upon the use of such construction.

In the accompanyi g drawings: Figure 1 is aside elevation of a portion of a tire shoe, the same being partly broken away to show the fabric construction. Fig. 2 is a similar view, showing a slightly modified construction. Figs. 3, 4, 5 and 6 are transverse sectional views of portions of tire shoes, show-A ing different embodiments of our presentinvention. y Figs. 7 and 8 are views similar to Fig. 1, showing still other modifications. Figs. 9, 10 and 11 are detail views of different forms of threads or cables.

1, the fabric or thread layers the reference numeral 1 'deinner layer or layers of fabric ofv .radially disposed cable laid by weak weft In the said drawings, referring particularly to Fig.

noting an composed 2 of the ordinary lwoven used in tire' shoes, said fabric layer or layers being disposed diagonally or on the bias in the well known manner. 0n top of the fabric layer or layers 2 we dispose a layer or layers of fabric 3 like the fabric 2, but disposed radially. The ends of the cords and the edges of the fabric around beads whichforin comfor the` cords ,and fabric. In Fig. 2 we have shown theinner layer or layers of radially disposed cable laid warpthreads 1,r as in Fig. 1, but with-the tire fabric commonly layer or layers 'of fabric 2 and 3 transposed, y the bias layer or outside ofthe ayers 2 lyin we wish it to radial layer or layers 3. An

York, have' fabric' in conjunction with plies of ordinary fabric,

be understood that we contemplate dispensing with either of the layer or layers 2 or i3, using but one of them, and we also contemplate using one or a plurality of the layers. 1, 2 or 3, reserving the right to vary the saine as maybe found desirable.

'hile we have shown the layer or layers of fabric 2 and 3'of comparativelynarrow width in Figs. 1 and 2, we do ourselves to any particular width for said layer or layers, as the same may be varied within the widest limits possible in tire construction. z

In Fig. 3 we have. shown a plurality of radially disposed inner layers G of cable laid threads-like the layer or layers 1 of Fig. 1, and on the outside of the rubber 7' covering the same a layer of ordinary fabric 8. the same terminating preferably short of the tread, as shown.

In Fig. 1 are shown two inner' 'layers 9 of ordinary fabric and a pli` ality of layers 10 of radially disposed cabls laid threads; in Fig. 5 an outer layer 11 of ordinary fabric and a plurality of inner layers 12 of radially disposed cable laid thread; an in Fig. 6 a single layer 13 of ordinary fabric interposed between outer and inner layers 1l of radially disposed cable laid thread. 'ith respect to all of these constructions. however, we contemplate any variation in the number of layers of and fabrics, as, for instance, the employment of a plurality of layers of the ordinary with one or more layers of the cable laid thread, or any other variationas to the respective number of layers of the same.v "5.

The primary object of sti-actions is to minimize any yielding or swaying of the tire shoe sideia'ise when in use, it having been found in practice that vantages otherwise over tire shoes formed are more given to lateral yield, which it is desirable to minimize. l

1We have found that very satisfactory results can be obtained by employing, instead .of cable laid threads, 4a one-ply thread, as

shown at 19 in Fig. 7 and which may be employed, radially or .more layers, and in conjunction with a not confine the respective threads all of these\ contire shoes made up of radially disposed` threads alone, while possessing distinct addisposed as shown, m one as shown. And we ,contemplate the arrangement of said threads in slightly separated groups, as shown at 21 in Fig. 8. 0r thesaid one-ply threads 19 may be loosely twisted into a cable 22, as shownin Fig. 10, or assembled in groups 23 untwisted und tied at intervals at 24, as shown in Fig. 11.

Having thus described our invention, what we claim as new and desire to secure by Let? ters Patent is: Y

1. A tire shoe embodying as the textile portion thereof radially disposed tilanientary elen'lents, fabric holding the elements againstside sway, and beads around whichthe terminals Copies of this patent may be obtained for In Fig. 9 We have shown this one diagonally disposed woven tire,

of the'elcments and the edges of the fabric are disposed.

2. A tire 'shoe embodying as the textile portion thereof radially disposed cabl luid :2&5
